Here are a few progress photos from my build. It may look a bit silly at first... but God willing it'll turn out in the end.
This first photo shows a thinned-down piece of titanium. This piece started at a bit more than 0.20" thick, and I needed to work it down to ~0.15"-0.16". I used a 2" face mill, but as you can see, it left a fairly rough finish. I decided that the ridges left by the face mill were too pronounced to give be a flat base for spotting my holes, so here I am using a 5/32" carbide end mill to create some flat "dots".
Next, I am using a 1/4" carbide spotting bit to start the holes where they need to go.
Here I am drilling all the holes to size. I use mostly cobalt bits for this. I managed to smoke one of these bits by accidentally using carbide speeds. Ouch.
This photo shows all of the holes drilled and the start of the insert slots milled.
This photo may look much the same as the last one, with the following changes:
- Insert slots have been step-milled to 3/16".
- (6) accent/skeletonize holes have been countersunk.
- All other holes have been reamed and counterbored for hardware.
This photo was taken after I flipped the plate over and did a few counterbores on the back side. I have removed the Ti plate from the mill and glued my printed CAD template onto the piece. I used one of my fluorescent fixtures as a light table to make sure all of the holes lined up.
And this is the last photo from this update. I ran the plate through the bandsaw - demolishing a not-insignificant number of bandsaw teeth in the process - to cut the handles to rough-shape.
I see some blade work and a great deal of nasty titanium grinding in my future.
